Hypoventilation may be caused by an uneven distribution of inspired air (as in bronchitis), obesity, neuromuscular or skeletal disease affecting the thorax, decreased response of the respiratory center to carbon dioxide, or a reduced amount of functional lung tissue, as in atelectasis, emphysema, and pleural effusion.
Seborrheic Keratosis Causes Wart Like Skin Growths. Seborrheic keratosis causes wart like skin growths to appear on just about every body thatâs over age 40. Although they resemble skin cancer, these keratosis tumors are benign.
These include: 1  Common wart (Verruca vulgaris), a raised wart with roughened surface, most common on hands, but can grow anywhere on the body. 2  Flat wart (Verruca plana), a small, smooth flattened wart, flesh-coloured, which can occur in large numbers; most common on the face, neck, hands, wrists and knees. Filiform or digitate wart, a thread- or finger-like wart, most common on the face, especially near the eyelids and lips.
